When the pair of clamping plates 407 abuts against the workpiece, it will drive a pair of sliding rods 408 to slide on the limit plates 406 and compress the spring 409. After clamping, the workpiece remains centered and stably placed, thereby realizing the correction of the workpiece. Then the user starts the water pump in the circulation box 6 to pass the working fluid through multiple The nozzle 7 is transported to the inner cavity of the processing table 1 so that the workpiece is immersed in the working fluid. When the workpiece is processed, the user controls the correction component 4 to release the clamping of the workpiece, and then controls the first electric push rod 3 to drive the placement plate 2 to lift, so that the workpiece is separated from the working fluid and comes to the upper side of the processing table 1, and then starts the hot air blower 5 to heat the workpiece, so that the working fluid attached to the surface of the workpiece evaporates quickly. At the same time, the hot air output by the hot air blower 5 can blow away the debris that may remain on the surface of the workpiece. Then the user controls the second electric push rod 12 to contract, driving the baffle 13 to slide upward to expose the drain hole 11. The working fluid in the processing table 1 is discharged into the drain pipe 9 through the drain hole 11, and then discharged into the filter 10 through the drain pipe 9. The debris in the working fluid is intercepted by the filter plate 14, and the filter 10 filters and recycles the working fluid. The treated working fluid will be discharged into the circulation box 6 again for the next use.
